Remote control mechanism for timepieces

1. A timepiece control mechanism for the remote control of an axially and rotationally movable main stem for operating a timepiece movement, said control mechanism comprising:

a secondary stem arranged to be operated by a user to control the motion of said main stem; and

said control mechanism comprising a plate arranged to be secured to a said movement or to form a structural element of a said movement; said plate including:

a rotation guide that guides rotation of said secondary stem, and

an axial stop that stops axial rotation of a secondary pinion, said secondary stem being free in translation and integral in rotation with said secondary pinion;

said control mechanism further comprising:

a transmission train meshed with said secondary pinion and arranged to transmit any rotation of said secondary pinion to said main stem; and

an articulated connection arranged to transmit any axial motion of said secondary stem to said main stem,

wherein said articulated connection includes, at a first end, a first lever pivoted about a first axis and, at a second end, a second lever pivoted about a second axis, said first lever being articulated to said second lever by an intermediate articulation, said first axis being spaced from said second axis,

said first lever being articulated at said first end with said main stem,

said second lever being articulated at said second end with said secondary stem.

2. A timepiece control mechanism for the remote control of an axially and rotationally movable main stem for operating a timepiece movement, said control mechanism comprising:

a secondary stem arranged to be operated by a user to control the motion of said main stem; and

said control mechanism comprising a plate arranged to be secured to a said movement or to form a structural element of a said movement; said plate including:

a rotation guide that guides rotation of said secondary stem, and

an axial stop that stops axial rotation of a secondary pinion, said secondary stem being free in translation and integral in rotation with said secondary pinion;

said control mechanism further comprising:

a transmission train meshed with said secondary pinion and arranged to transmit any rotation of said secondary pinion to said main stem; and

an articulated connection arranged to transmit any axial motion of said secondary stem to said main stem,

wherein said articulated connection includes, at a first end, a first lever pivoted on said plate and, at a second end, a second lever pivoted on said plate, said first lever being articulated to said second lever by an intermediate articulation,

said first lever being articulated at said first end with said main stem,

said second lever being articulated at said second end with said secondary stem, and

wherein said first lever forms a first pull-out piece with said main stem, and said second lever forms a second pull-out piece with said secondary stem.

3. The control mechanism according to claim 1 , wherein

said articulated connection includes only said first lever, said second lever, and said intermediate articulation, and

said intermediate articulation directly connects said first level to said second lever.

4. The control mechanism according to claim 1 , wherein said control mechanism comprises a main pinion arranged to be mounted freely in translation on said main stem and integral in rotation therewith, and wherein said transmission train is meshed with said main pinion.

5. The control mechanism according to claim 4 , wherein said transmission train comprises, at least one third intermediate wheel interposed between a first intermediate wheel arranged to cooperate with said main pinion and a second intermediate wheel arranged to cooperate with said secondary pinion.

6. The control mechanism according to claim 5 , wherein said at least one third intermediate wheel includes only one third intermediate wheel interposed between said first intermediate wheel and said second intermediate wheel.

7. The control mechanism according to claim 5 , wherein said one third intermediate wheel is an annular wheel arranged to be fitted around said movement.

8. The control mechanism according to claim 1 , wherein said plate is a case middle arranged to contain said movement.

9. A watch comprising at least one timepiece movement comprising an axially and rotationally movable main operating stem, and a control mechanism according to claim 1 .

10. The watch according to claim 9 , wherein said main stem is a setting and/or winding stem.

11. A timepiece control mechanism for the remote control of an axially and rotationally movable main operating stem of a timepiece movement, said control mechanism comprising a secondary stem arranged to be operated by a user to control the motion of said main stem; a plate arranged to be secured to a said movement or to form a structural element of a said movement; said plate including a rotation guide that guides rotation of said secondary stem, and an axial stop that stops axial movement of a secondary pinion, said secondary stem being free in translation and integral in rotation with said secondary pinion, said control mechanism further comprising a transmission train meshed with said secondary pinion and arranged to transmit any rotation of said secondary pinion to said main stem; an articulated connection arranged to transmit any axial motion of said secondary stem to said main stem; and a main pinion mounted freely in translation on said main stem and integral in rotation with said main pinion, said transmission train being meshed with said main pinion, wherein said transmission train includes at least one third intermediate wheel interposed between a first intermediate wheel arranged to cooperate with said main pinion and a second intermediate wheel arranged to cooperate with said secondary pinion, and wherein said at least one third intermediate wheel is an annular wheel arranged to be fitted around said movement.
